Be it known that l, 'ltuoos'r lvlnnilrean, a citizen of the United States of America, re siding at Pittsburg, in the county. of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Window-Cleaners for Cars, of which the following isa specification, reference being had therein to the accompanying drawing.

This invention relates to a window cleaning device, particularly designed for the windows of a street car located in front of the motormanor operator of the can The primary object of my invention is to provide a window cleaning device that can be easily and nickly manipulated by the 1notorman of tie street car for removing snow, sleet, frost, water and dirt from a window, whereby his View will be unobstructed, and the liability of a person being run down. by the car due to the motormans attention be-- 'ing obstructed reduced to a minimum.

Another object of theinvention. is to pro vide a window cleaning device that can be manipulated from the platform of a car, without opening a window or leaving the platform.

lll device besides being up glicablc to the windows located at the ends oi the car is also applicable to the windows of passenger. railway-coaches, and the windows of locomotive cabs. i

The above objects are attained by a struc turc that will be resently described in detail and reference wil now be had to the dra ing forming a part of this application, wherein, Figure l is an end view of a portion oi a street railway car equipped with my window cleaning device, Fig. 2 is a transverse sectional view of a portion of a window-sash illustrating a portion of my device, Fig, 3 is a vertical sectional view of the same, 4 is a perspective view of one of the slide bearings used in connection with my device, and Fig. 5 is a perspective view of a portion. olia strip holder.

In the accompanying drawings, 1 desigmates the central window-frame of a street railway car, this window-frame having a sash 2 provided with a pane of glass 3.

To put my invention into practice, 1 providethe sash 2 with rectangular frame 3 having the side rails 4 thereof provided witha vertical groove 4 Attached to the rails l,

at the upper ends thereol, are brackets 5 for supporting a spring roller 6 ol' a conventional Letters Patent.

form. Attached to this roller and adapted through slide bearings 8 movably mounted in the vertical grooves 4. The cables 7 are secured in the slide bearings 8 by set screws 9, and then extend downwardly through transverse openings 10 to the central portion of the frame 3, and from these openings the cables exte'ml through a central 0 ening 11 provided therefor in the sash 2. T 1e ends of the cables are connected together andare of a length sullicient fora. motorman to rip the same, pull downwardly and lower t a slide bearings 8 in the grooves 4 To weer upon the cables 7, the outer on s of the openings 10 are rounded, as at 12. The slide bearings 8 are Tsshaped in elevation and one of said bearings is rovided with a socket l3, while the opposite caring is grooved, as at l The socket l3 and the groove i l are adapted to receive the ends of a strip holder, said holder comprising two flat members 15 and 16, between which is arranged a resilient strip of rubber 17. The strip of rubber 1? and the members l5 and 16 are held together by bolts 18 and nuts 19.

Set screws 20 are einployedfor holding the ends of the strip holder in the T- shaped slide bearings 8.

The frame 3" is provided with a curved shield 21. for protecting the s ring roller 6.

The resilient strip 17 normally engages the windowlane 3 and is held in engagement therewith adjacent to the upper edge of said window'sash by the spring roller 6. An accumulation of frost or snow upon the windowpane 3 is removed by the motorman ulling upon the cables 7, and since said cab es are secured in the slide bearings 8, the resilient strip 17 will be carried downwardly over the window vane 3. When the cables 7 are released, the 5 ring roller 6 immediately retion, ready to be again used upon matter accumulating upon the window-pane it will be observed that it is only necessury to rovide a window-sash with an opening in O1L or that my device can be used in connec tion therewith, and that by providing the extra frame 3, the device can be removed during the summer months, and simply used men are troubled by snow and similar mat ter coating window-panes In order that water and snow removed from the Window-pane 3 will not accumuleto to wind thereon are cables 7, which extend revent turns the resi lent strip 17 to its normal posi during the winter months when the motor upon the frame 3, the lower part of said frame at the inner edge thereof is provided with a plurality of vertical openings-22.

While in the drawings forming a art of this application there is illustrated t \0 preferred embodiments of my invention, 1t is obvious that the same can be varied or changed as to shape, lproportion and manner of assemblage wit iout departing from the spirit of the invention.

Having now described my invention, What .I claim as new, is

1. The ombination of a frame adapted to be secured to awindow sash, said frame having the side rails thereof )rovided with vertical gro0ves,Tshaped sfide bearings movably mounted in said grooves, a strip holder detachably supported by said bearings, said holder comprising two members, an inter posed resilient strip adapted to normally engage said window-pane, and bolts for securing said members and said strips together;

a spring roller supported at the top of said frame and between said side rails, eables at tached to said. spring roller and adapted to wind thereon, means for attaching said cables to said bearings, said frame having openings formed therein to receive the ends of said cables, and a shield carried by said frame for protecting said spring roller, substantially as described.

2. The combination of a frame adapted to be secured to a Window sash, said frame hav ing vertical grooves formed therein and further having openings, bearings slidably tachahly connected to said hearings, a resilient strip detachably connected to said holder and adapted to engage a window pane, a spring roller arranged in said frame at the upper end thereof, and cables attached to said roller and to said bearings and adapted to extend in said openings.

In testimony whereof 1 MILK my signature l in the presenre of two witnesses.
